Tb dzz-wamamy m -g i B it known that'I ThomsAJm'r, a

citizen of the United States o'trimencmand a. resident of Gr'enville, county of Bond, State of Ill1l101S l12tY invented certain new and useful Improvements moan; Soldering hlachines of'whicli tliefolloiviiig is a specification. I p

This, invention relates to an improvement in soldering machines and has" its Inary object the purpose of; providing iin provei'nents machines of the.- character known tip solder ng in which a s'ingle opening in the can top of each filled can. is

tipped and soldered by a single engagement of the soldering tool as each fill'e'd can is engaged thereunder.

Another object of the invention is in providing an improvement in a soldering machine in which each can to be tipped is caused vto be brought to a stop in its travel while the soldering tool is operating thereon.

A further object of the invention is in providing the soldering tool with a renewable tip or soldering p'oint.

A still further object of the invention is in providing the soldering tool with a soldering point which is made of a particular kind of metal. I

Another further object of the invention is to provide improved feeding means forfeeding the solder to the soldering t'ool.

Other and further objects will appear in the specification and be specifically pointed out in the appended claims, reference being had to the accompanying drawings. exemplifying the invention, and in whichf:-

The tubular extension 50 is mounted within the Vertical portion 51 of a T-fitting 52 and secured to the upper end of said extension is an L 53 to which a gas supply line. 54 is connected.

Extended from the horizontal portion 55 of the T-fitting 52 is a short shaft 56, said shaft being rigidly secured to said fitting and turnably. within a pair of arms 57, said arms being rigidly extended from a rock shaft 58 which is turnably supported within a pair of vertically extending supports 59 which are in turn supported from the table 1.

Borne by "'the shaft are a pair of grooved guli 'ding rollers 84, each of said rgll e'rs 'beingjn opposite disposition to a respective" r fq'ved roller 85, said rollers being borne by' the short shaft 83, each pair of opposing-rollers 84 and 85 being arranged in close 'proximityto each other so as to provide guiding and feeding agents for the soldering material of which there are two strands 86 and 87 which are fed from respective drums 88 and 89 which are arranged on the shaft 90.

In the operation of this improved solderingmachine, filled cans are brought front the can filling machine by the conveying side '40 ofthe conveyor 6, said filled cans being moved on the surface of the table 2, said conveyorderiving its travelling motion from means (not shown) which may be geared from the can filling machine and coincident with the traveling of the conveyor 6 the driving shaft 8- is operated thereby'impartingmotion to the stub shaft 16 through the gears14 and 15, thereby imparting motion to the disk 18 and throw pin 19. On account of the connecting rod 20 being secured at one end to the pin 19 and at its opposite end to the rocker arm 23, rocking motion will be imparted to said arm and cause the connecting rod 28 to be reciprocated, and inasmuch as said rod 28 is connected to the cross head 31, said 15 caniiec ig Fre 7% t p mberslfi'di'sa gear 81, said the table 2 b'y'enga'gement of the can engiiging"portions 7 of the conveyor 6 therewith and in which said cans are moved along said table in spaced apart positions, the upper projecting'er'ids 38 of the pair of dogs carried by "the cross head 31 will engage each can as each. can is brought up to a position wherein it will "be engaged by. said dogs at the end of the rearward stroke of the cross head 31. The cross head 31 is designed to travel at a greater speed than the conveyor 6 and after a can has been engag'ed by the extending ends of the do 35, the cross head 31 is moved forwardly thereby forcing the can forwardly and away from the can'engaging portion 7 of the conveyor, said cross head conveying the engaged'ca-n forwardly until it has reached the end of its forward stroke, said cross head on its return stroke leaving the ic'an moved thereby in a stopped position directly beneath the soldering tool 47. Immediately after the filled can has been deposited be neath the soldering tool, the eccentric 11 which is located on -the dri e sha ft 8 'Will cause the rock shaft 58 to be rocked thereby lowering the arms 57 which sustain the solderin'sr tool 47, said soldering tool being directed in its travel to the centrally arranged opening formed in the can top by engagement of the guiding member with the set screw 61. the soldering point 91 of said tool while descending engaging both of-the s0ldered lengths 86 "and '87, as shown more clearly in Figs. 1 and 2, said tool depositing the solder over the can opening or aperture.

It is obvious that as soon as solder has been deposited from the tool 47 over the can opening which is to he soldered, said tool will be elevated by the action of the eccentric 11 upon the connecting rod and rockshaft 58, and as soon as the tool has become disengaged from the can. the can engaging portion 7 from which the can was dise'ngaged by actuation of the dogs 35 of the cross head 31, the soldered or sealed can Will he again engaged by its respective can enfl'flfflnfl' portion 7 and moved forwardly from beneath the soldering tool.

As the cross head 31 was moved rearwardlv after the depositing of the can re ferred to beneath the soldering tool, the projecting: ends 38 of the dog 35 will engage the bottom of the next can in the order of travel, the weight of said can causing the dogs 35 to swing as the cross head 31 is moved thereunder. but as soon as the projecting ends 38 of the dogsbecome disengaged from beneath the bottom of the can they will immerliatelv be swung upwardly bv the balancing weights thereof. so that said projecting ends of the dogs will engage the lower edge of t'liurst'jcan in area when the end reaches the endret its rearward stroke. I n the new. 'ferwar'a have of the'cios's' head 31 the second can in order will be' carried forwardly may froth its respective 'c'an engaging portion 7 6f the conveyorti and he deposited beneath the soldering =tool 47 so'that the aperture thereof can be sealed o'rsoldered by 'erigagefment of the soldering tool thereto in the manner as was the first ca'n above mentioned. I v V *Ftr fproperly jidsifiioning c'ans beneath the soldeihig to'o'l 47, side guidifig members 92 are provided, and 'for firin'ly seating the cans on 'the tahle 2 as they are brought up by the soldering iron anddu'ring the operating of the irdnthereon, the pressure bars 42 are provided. I

.As the solderin tool 47 is inoved u'pwardly after a solder operation, the solder lengths 86 and 87 are fed forwardly in the path of travel thereof. The feedingjfdfi war'doftue Soldering 86 87 'i's intermittent and is brought about by factuation of theeceentric 12 of the drive shafts 'o eratii ppdfi the connecting rod 72 and roekei-jarinr' t, "said rocker a rm causing the awr 79:10 drag a maes ro-0th of the ra'tchetwheelTS and turn said wheel.

me the intermittent turning of the 'i-at'c'i c wheel 78 tagger-r81 which isin mesh with tl'iegear 82 will'ca'use said gears to'he turried and the opposing zroovedrollers8 t and 85 will be OT'Sera ted in pairs therewith thereby feeding the snlderlengths 86 and 87 to the Ql i 9 When it is desired to laterally adjust the soldering tool 47 the thumbset screw 66 is engaged and manipulated and the disk "63 to which said. thumb screw is extended will he moved and cause the shaft 58 to be moved said lateral adjustment being for the purpose of properly positioning the soldering point 91. of the 'tool in direct ali'nement with "the can aperture to he soldered.

The soldering point 91 is provided with a threaded shank 93, said shank being engaged in the threaded opening 94 which is formed in the tool. said threaded shank providing means for removing the soldering point for the purpose of renewal. The renewal operation is brought about by driving the body of the soldering tool from the head 49 of the tubular extension 50. and engaging a screw driver in the heating chamber 48 of 'the tool and seating the point of the screw driver in the slot 95 of the shank 93, thereby forcing the soldering point 91 from the soldering 'tool. A new soldering point is then inserted in the opening 94: of the soldering tool. y

The soldering point 91. special in the specific kind of material from which it is made, said material being Monel inetal and the holder or body portion 96 of the 'tool being cast iron. In the use of Monel metal as a soldering engagingpoint for soldering tools, it has been found that the Monel point willretain and hold a maximum amount of solder as against other metals which will invariably drop or lose an amount of the solder.
